 GDB was introduced with its Python support early 2011 with the release of GDB 7. A (very) long way has gone since and the Python API has been massively improved, and GEF is taking advantage of them to provide the coolest features with as little performance impact as possible.
 
-Therefore, it is highly recommended to run GEF with the latest version of GDB. However, all functions should work on a GDB 7.7 and up. If not, send a [bug report](https://github.com/hugsy/gef/issues) and provide as much details as possible.
+Currently, GEF is optimized for running against GDB version 8.0+, and Python 3.6+. This allows for a best performance and best use of the GDB Python API. However, GEF can run on older versions too, check out [the version compatibility matrix](compat.md). For really older versions of GDB, you can use [`gef-legacy`](https://github.com/hugsy/gef-legacy) which supports a lot of older GDB, and a Python 2/3 compatibility layer.
 
-If you are running an obsolete version, GEF will show a error and message and exit. You can still use GDB the normal way.

 Some pre-compiled static binaries for both recent GDB and GDBServer can be downloaded from the [`gdb-static`](https://github.com/hugsy/gdb-static) repository.
 
-_Note_: although some Ubuntu versions are marked as version 7.7 they are actually compiled with some missing features that will make `GEF` complain of an error. Before lodging a bug report, make sure to update your GDB (via APT is fine), or better install `gdb-multiarch` (the package `gdb64` will work as well, but is considered obsolete).
 
 ## I cannot get GEF setup!! ##
 
-GEF will work on any GDB 7.7+ compiled with Python support. You can view that commands that failed to load using `gef missing`, but this will not affect GEF generally.

 If you experience problems setting it up on your host, first go to the [Discord channel](https://discord.gg/HCS8Hg7) for that. You will find great people there willing to help.
 
 Note that the GitHub issue section is to be used to **report bugs** and **GEF issues** (like unexpected crash, improper error handling, weird edge case, etc.), not a place to ask for help.
 
-But fear not, GDB 7.7 corresponds to the latest packaged version of Ubuntu 14.04. Any version higher or equal will work just fine. So you might actually only need to run `apt install gdb` to get the full-force of GEF.
